   While driving home from work the car displayed a "No Fuel" warning, despite having a full tank of gas. Within seconds of the display showing the car stalled out and stopped right in the middle of the road. It would not go into neutral and I had to be towed from the middle of the road to a mechanic close by. Upon reading forums online it looks like this is a known and common issue affecting the fuel pump sensor and system in these models. There are no open recalls but being…

   I have seen numerous complaints for this same issue. My 2021 Acadia with 31,600 miles failed to start when parked in garage. It turned over just fine but wouldn't fire as if it wasn't getting any fuel. I had it towed to my regular mechanic. He troubleshot it and told me it was the "Fuel Pump Power Control Module". He said he could replace it but it would have to be programmed by a GM dealer as he didn't have the equipment to do that. So I had it towed to the local GMC…
